The answer is C.

Class 7 Question

Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. It seems so commonplace that we rarely spare a thought for that bright object in the sky. Yet without it, we wouldn’t exist! so sun is a ultimate sourse of energy.

✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.

✴Secondly, sunlight is a good source of Vitamin-D.

Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.

✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

Sun is the ultimate source of energy for all living organisms. Because of the sun only we are living on earth, and all living organisms are living. Because of the sun this flowers are blomming , all this fruit are coming.

Solar Energy: The Ultimate Power Source. Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. ... Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities

Sun is the correct answer because the heat from the sun radiates to the earth which is required by plants for photosynthesis and by organism to get nutritents example human being take the sun heat to get vitamin D and it is ultimate because it will take millions or billions time to finish over

This all answers are correct but one thing is Every morning the sun rises , bringing light and heat for the earth, and every evening sun sets. It seems so common places that we rarely spare a thought for that bright object in the sky . Yet without it, we wouldn't exist ! So SUN is a ultimate sourse of energy

The sun is the star in the center of our solar system.It is a yellow dwarf star.It gives off energy as light.That include light ,infra-red energy(heat), ultraviolet light and radio waves. ... The sun is about a hundred times as wide as the Earth. Option (C)

The answer is sun because without it there with be no growth of plants (as it uses the energy of sun to make its food)and most living being depends on plant for food and oxygen which makes us live so, sun is ultimate source for all.

The SUN is the ULTIMATE SOURCE OF ENERGY. Every morning the SUN rises, bringing light and heat to the earth, and every evening it sets. ... Plants convert light ENERGY from the SUN into chemical ENERGY (food) by the process of photosynthesis. Animals eat plants and use that same chemical ENERGY for all their activities.

The help of sunlight, plants make food. the animal are depends on plant's for food. the sunlight help moons are shinee. the sunlight is not present in Atmosphere, the plants is not makes food, so plants is died. the animal is not take the food from plants. so, animal is dies.
